In this study, it was aimed to compare the antioxidant properties of extracts obtained from extraction olive leaves in Hatay province prepared with different solvents. For purpose, were extracted using pure methyl alcohol soxhlet and also by maceration 60% ethanol, 70% methanol, 90% acetone (v/v) distilled water. Total Flavonoid Content (TFC), Phenolic (TPC), Ferric Antioxidant Reducing Power (...

The chloroform and alcohol extracts of e plats were screened against six bacteria viz staphylococcus aureus, Escherichia Coli, proteus mirablis, salmonella typhimurium, Pseudomonas aeruginosa and Klebsiella a aerogenes. Benzene-ethyl acetate (4:1) eluate of chloroform extract sowed activity against E.Coli, S.typhimurium and P.aeruginosa. The nbutanol extract of alcohol extract was active agains...

1. Pepsin is soluble in 65 per cent alcohol and may be readily crystallized from 20 per cent alcohol. The crystals appear as needles or plates which may be transformed into the usual hexagonal bipyramids by recrystallization from water. The different crystals are probably two crystalline forms of the same chemical substance. 2. The enzyme is quite stable in 20 per cent alcohol at pH 2.0 but is ...

In male Wistar rats the hepatoprotective effect of pollen extracts (Cernitins) agains. orally introduced 1% allyl alcohol (0.4 ml per 100 g body weight) was investigated Cernitins were applied orally at 0.6, 24 and 30 h after allyl alcohol administration. After 48 h an autopsy was performed and blood was collected for biochemical tests. Liver damage was evaluated by measurement of aminotransfer...

Pneumococcus extracts highly active in inducing the in vitro transformation of the specific types of Pneumococcus have been prepared by dissolving S cells with sodium desoxycholate, precipitating the dissolved material in alcohol in which the bile salt remains soluble, and extracting the precipitate in salt solution. Further purification of these active extracts has been attained by the removal...

OBJECTIVE To evaluate the in vitro antifungal activity of Aegle marmelos leaf extracts and fractions on the clinical isolates of dermatophytic fungi like Trichophyton mentagrophytes, Trichophyton rubrum, Microsporum canis, Microsporum gypseum and Epidermophyton floccosum. METHODS The minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC) of various extracts and frac...

Sugarcane tops were extracted with 50% ethanol and fractionated by petroleum ether, ethyl acetate (EtOAc), and n-butyl alcohol successively. Eight phenolic compounds in EtOAc extracts were purified through silica gel and Sephadex LH-20 column chromatographies, and then identified by nuclear magnetic resonance and electrospray ionization mass spectra. The results showed that eight phenolic compo...

BACKGROUND Strychnos nux-vomica, commonly known as kuchla, contains strychnine and brucine as main constituents. Minor alkaloids present in the seeds are protostrychnine, vomicine, n-oxystrychnine, pseudostrychnine, isostrychnine, chlorogenic acid, and a glycoside. Seeds are used traditionally to treat diabetes, asthma, aphrodisiac and to improve appetite. OBJECTIVE The present study was aime...

Halobates is the only insect genus with representatives in the open ocean. How adults find one another at sea has long been an intriguing issue. Since chemical communications have been demonstrated in a related marine veliid Trochopus, and laboratory bioassays indicated behavioral differences between males and females when insect extracts were presented, we carried out similar studies on Haloba...
